The introduction of competition into utilities is currently being purs
ued in the many countries, including the UK. Competition can lake vari
ous forms, such as competition for outputs, inputs, franchises, and ou
tright takeovers. Attention is currently focused on output competition
, whereby customers are being given a choice of final supplier in many
industries. We consider the implications of the introduction of such
competition, including the effects on industrial structure and contrac
ts, cross-subsidies and distributional concerns, and uncertainty and s
tranded contracts. We also analyse the transitional problems encounter
ed as competition is introduced and suggest that the UK regulators and
government have, in some key respects, failed to define a clear and c
onsistent policy.
